Original Post
I have noticed that other posts have been made on this topic but i am not able to understand how to implement it. I am trying to make a simple 2d game with a flying jet; at the moment it is just a square block. The problem is I would like to be able to able to press multiple keys at once.
Below is the code, i would graetly appreciate if anyone could give any ideas, advice or anything which would start the ball rolling.
Many Thanks in advance
